1、 Book6 Unit3 Grammar: The Usage of “It”教学设计一、高中英语课程标准分析:普通高中英语课程标准明确要求掌握宾语从句、主语从句和强调句型,其中主语从句和宾语从句在it作形式主语和形式宾语句型中最难掌握。而且其用法是中学阶段英语学习的主要语法项目之一。纵观历届高考题,无论是单项选择,还是完形填空,it用法始终是反复考查的重、热点之一。二、教材分析 这节课的内容是高二上学期选修六第三单元中关于it用法的综合讲解。It是一个比较灵活的知识点,用法多样复杂,尤其是it作为形式主语和形式宾语的用法,如果掌握不好会影响句意的理解,以及一些高级句式的表达。 三、学情分析:
2、It的用法已经给学生强调了很多,本课主要是在讲解人教版选修6课本第三单元的课文中带有it的句子,因此学生对it的用法相关知识有一定基础。在此基础之上引导学生进行学习、归纳、总结和应用。四、教学目标:依据新课标要求和学生的认知特点,设定如下目标:1、知识目标:学习it的用法,正确分辨出含it的常用句型,提高解题速度。2、能力目标:能正确的使用包含it的各种句型,使学生形成良好的语言习惯。3、情感目标:通过课上师生互动和生生互动,增强师生之间的感情。使学生能够体会到学习英语的目的在于交流和应用。五、教学重点和难点:1.“it作为形式宾语和形式主语的用法”是本课的重点。2.归纳出it语法句型的规律是
3、本课的难点。六、学习方法及教学策略分析:主要使用了归纳法,讲练结合,采用多媒体教学的辅助功能。七、教学过程:本节课让学生通过自主学习和合作学习获得知识,用多媒体教学手段加上黑板的使用来突破本课的重难点。本课设计了五个环节:1.热身和导入环节:通过it作为代词的最基本的用法引入各种it作为形式主语的各种句型,来让学生分析和总结概括。2.讲练结合:通过练习对it作为形式主语的各种句型做进一步的了解和巩固,然后引入it作为形式宾语进行讲解。3.归纳和巩固练习:通过展示各种不同的句子,先概括it作为形式宾语和强调句型的句法结构,然后加强练习。4综合练习:在讲完it的以上用法之后,进行练习来巩固所学知识

Have you heard about (it)? b.泛指时间、日期、距离、天气、地点、温度、距离、环境等。 It was nearly midnight when she came back.It is noisy here. It is about twenty minutes walk from
5、here to the bus stop. II. 引导词: a. 作形式主语, 代替由不定式, 动名词或从句表示的真正主语。其基本句型为: It (形式主语) +adj. + to+ v. It (形式主语) +adj. + that (subject +v. ) e.g. It is important to know your limitations.

7、angs house.I found it very interesting to study English. He made it clear that he was not interested in this subject. II I.用于强调结构 要强调句子的某一部分, 通常是主语、状语、宾语, 可以把it当作先行词。这种句子的结构是: “It is/was+被强调部分+that/who+句子的其他部分”。如果强调的是人,可以用who, whom代替that。e.g. I met Tom in the street yesterday It was I who (that) met
8、 Tom in the street yesterday. It was Tom that I met in the street yesterday. It was in the street that I met Tom yesterday. It was yesterday that I met Tom in the street. It的一些习惯用法How is it with your study? Thats it. 这就对了。It went hard with him. 他身遇不幸。It is all over with me. 我完蛋了。We must fight it out. 我们必须坚持到底。I cant help it. 我没有办法。口诀:代词 it 本意它, 既可指这又指那;时间天气均可指, 谈到距离也用它; 假主假宾均可做, 强调句型跟that。Homework1.
